What it does:
Int.TryParse tries to convert a string into an integer (int).
It returns true if the conversion is successful, otherwise, it returns false.
It does not throw an exception if the input is invalid — very safe to use!
Syntax:
bool Int32.TryParse(string strValue, out int result);
strValue → The input string you want to convert.
result → The output variable where the parsed integer will be stored if successful.
Example Code:-
using System;
namespace ConsoleAppVerifyInput
{
internal class Program
{
static void Main(string[] args)
{
//int.TryParse()
bool a = true;
do
{
Console.Clear();
Console.WriteLine("Enter Any Number :-");
string strValue = Console.ReadLine();
if(int.TryParse(strValue,out int NumValue))
{
Console.WriteLine($"User Input Number is {NumValue}");
a = false;
}
else
{
Console.WriteLine("Invalid Number");
}
Console.ReadKey();
} while(a);
}
}
}
How it Works:
If the user types 123, TryParse stores 123 in the number, and isValid is true.
If the user types abc, TryParse fails, number is 0, and isValid is false.
Why use TryParse instead of Parse?
Parse (like Int32. Parse) throws an exception if the input is invalid.
TryParse avoids exceptions — it's safer and better for real-world apps!
